for my civic with a gsr motor swap i got a magnaflow muffler and a 12inch resonator. its a straight through muffler, and i am starting to realize this is probably going to be a lot louder then i was going for in the first place. the car already has 2 inch piping on it. if i want to keep this as quiet as possible what should i do. put the muffler on the 2 inch piping of get all 2.25 inch piping put on with the resonator and muffler. would it be better to get a better resonator?
